Predicting Cardiovascular Risk Factors for Acute Leukemia Patients by Assessing Subclinical Atherosclerosis and Left Ventricular Function Before Chemotherapy.

BACKGROUND

Subclinical atherosclerosis is a "silent" cardiovascular disease that can be devastating when combined with other illnesses. Its presence may affect therapy responses but can potentially worsen hematological malignancies due to most chemotherapy regimens' cardiovascular adverse effects. Thus, cardiovascular risk factor (CVRF) assessment is required before chemotherapy. Unfortunately, this rarely happens.

AIM

we aim to examine the impact of CVRFs on hemodynamic parameters of acute leukemia (AL) patients before chemotherapy.

METHODS

Overall, 45 AL patients and 26 controls were included. Intima-media thickness (IMT), ankle brachial index (ABI), pulse wave velocity (PWV), and functional cardiac parameters were used. CVRFs were found in 26 AL patients (36.6%), while 19 AL (26.8%) patients lacked CVRFs. CVRFs were also found in 26 controls (36.6%).

RESULTS

Left ventricular ejection fraction (LVEF) significantly decreased for patients with CVRFs (59.26 ± 5.62) compared to those without CVRFs (64.05 ± 7.43, < 0.05). Hypertensive and diabetic patients had a significantly higher left IMT (mm) of 0.92 ± 0.01 compared to those without them (0.76 ± 0.03, < 0.05). Patients with acute myeloid leukemia (AML) with CVRFs had a significantly higher PWV (m/s) of 8.4 ± 0.12 compared to those without CVRFs (6.87 ± 0.66) ( < 0.05).

CONCLUSIONS

AL and cardiovascular risk factors interacted before chemotherapy. To decrease cardiotoxicity, AL patients need cardiovascular risk assessment. Subclinical atherosclerosis and echocardiography help chemotherapy patients to choose a treatment regimen, predict long-term outcomes, and predict cardiovascular issues.
